First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial tests the safety of combining the targeted drug abemaciclib with various other breast cancer treatments (like letrozole, tamoxifen, or trastuzumab) in 198 people whose breast cancer has spread. The goal is to find safe combinations that may help control the disease. Participants have either hormone receptor-positive or HER2-positive metastatic breast cancer.

abemaciclib (a targeted cancer drug) combined with other drugs like letrozole, anastrozole, tamoxifen, exemestane, everolimus, trastuzumab, LY3023414, fulvestrant, pertuzumab, loperamide, or ongoing endocrine therapy

What this could lead to

If successful, this could help identify safe and effective drug combinations for treating metastatic breast cancer, potentially improving disease control.
